Older install with 3 LNB no signal but signal there.

Have a client with a 3LNB setup and everything is working great except 119 feed, replaced the LNB and now 119 is coming in strong all is well. Now i swap out the DVD player and power down the equipment rack to do this, power rack back up and now neither the D12 or older Hughes HTL-HD are working. In the setup menus I have all 3 sats at 92% or higher but when at the aquiring guide screens it says no signal and thats as far as it goes.

I am at a loss here unless the new LNB has died when power was restored to the sat receivers??

Does the screen say "no signal" or "771 searching for satellite signal"? If it is "no signal" then it is a message from the TV telling you that the TV is not getting a signal from the receiver, usually because the wrong TV input is selected or you are sending a signal resolution the TV can't handle...

The Hughes HDL-HT say channel not available and is stuck on the channel you select...enter 201 and it goes to 201 but says channel not available and wont channel up or down. When you run it through the setup it goes into the aquiring channel list and fails with a check your cables/connections, but yet it shows a 92-96 percent signal level on all 3 feeds

The D12 says it aquiring the data guide but sits at 00% and goes between no sat signal and aquiring data guide

I guess I can reinstall the old LNB and see if they come back online, if so sounds like it may be a bad LNB we installed.

I think I recall that DIRECTV receivers weren't able to figure out which satellites they were pointed at. I may recall incorrectly, but this would certainly explain the situation.

They're not. That's why when setting up a multi-satellite SD dish you monitor the signal strength of a transponder THAT ONLY EXISTS ON THE 101. The only way you will get a signal is if the dish is actually pointed at the 101 because it knows which transponders are available on each satellite.
